Run your QRP
rigs at full power when you are
traveling! Most rigs
are rated at 13.6-13.8V, and power output drops quickly as you get down
to 12V, as any battery user knows. This little gem is a real
powerhouse.
We tested the CUP-36 power supply
extensively in the Oak
Hills
Research
labs before selecting it as our standard power supply for use with the
OHR kits and accessories. With adequate grounding, we found
no trace of either RFI
emission
or susceptibility over the widest possible variety of loads.
We also
found the voltage to be a rock-solid 13.7V over the entire load range--
the 4% tolerance figure relates to the extremes of input voltage and
frequency. But note that proper operation of the filter requires your
equipment to be grounded (see application note
at the bottom of this page).
The CUP-36 is
smaller and lighter than a 7Ah gell cell,
and
will supply
2.4A at 13.5VDC continuous. With the
right AC power cord
or adapter you can plug it in anywhere in the world. The
supplied
AC cord is two-pin US standard.
The output
connector is 2.5mm coaxial, so it will plug
right
into any
OHR transceiver or accessory, as well as many other brands.
